BACKGROUND.: Subcutaneous panniculitis-like T-cell lymphoma (SPTCL) is a rare form of cutaneous lymphomas, accounting for less than 1% of cases of non-Hodgkin's lymphoma. Fluorine-18 fluorodeoxyglucose (F-18 FDG) positron-emission tomography/computed tomography (PET/CT) findings of SPTCL before and after treatment were rarely reported. CASE REPORT.: We report a case of SPTCL in which F-18 FDG ...

This pilot prospective evaluation study is to verify the efficiency of (18)F-Alfatide II, a specific PET imaging agent for integrin αvβ3, in detecting bone metastasis in human, with comparison to (18)F-FDG PET. Thirty recruited patients underwent (18)F-FDG and (18)F-alfatide II PET/CT successively within days. The final diagnosis of bone lesions was established based on the comprehensive assess...

68 Correspondence To the Editor: Dermatofibrosarcoma protuberans (DFSP) is a cutaneous soft tissue neoplasm of intermediate-to-low grade malignant potential. It arises from the dermis and invades locally into deeper subcutaneous tissue. It is characterized by a high local recurrence rate after standard surgical excision, partly due to asymmetric infiltration of the subcutis by delicate strands ...

PET with the glucose analog (18)F-FDG is increasingly used to monitor tumor response in patients undergoing chemotherapy and chemoradiotherapy. Numerous studies have shown that (18)F-FDG PET is an accurate test for differentiating residual viable tumor tissue from therapy-induced fibrosis. Furthermore, quantitative assessment of therapy-induced changes in tumor (18)F-FDG uptake may allow the pr...

Clinically, the most commonly used positron emission tomography (PET) radiotracer is the glucose analog 2-[(18)F] fluoro-2-deoxy-D-glucose ((18)F-FDG), however little research has been conducted on the biological effects of (18)F-FDG injections. The induction and repair of DNA damage and the relative biological effectiveness (RBE) of radiation from (18)F-FDG relative to 662 keV γ-rays were inve...

UNLABELLED The purpose of this study was to compare the diagnostic accuracy of glucose metabolism and amyloid deposition as demonstrated by (18)F-FDG and Pittsburg Compound B (PiB) PET to evaluate subjects with cognitive impairment. METHODS Subjects were selected from existing participants in the Mayo Alzheimer's Disease Research Center or Alzheimer's Disease Patient Registry programs. A tota...

UNLABELLED The purpose of this study was to assess the utility of (18)F-FDG PET/CT for detection of inflammation in granulomatous sites and management of patients with chronic sarcoidosis. The 3 specific aims were to assess differences between (18)F-FDG PET/CT and multidetector CT (MDCT) findings, to compare (18)F-FDG PET/CT results with serum levels of angiotensin-converting enzyme (ACE), and ...

UNLABELLED PET using (18)F-FDG has prognostic value when performed at the completion of initial chemotherapy in patients with diffuse large B-cell lymphoma (DLBCL). (18)F-FDG PET may also be predictive of outcome when performed during the treatment course of DLBCL, but robust prospective studies and standardization of (18)F-FDG PET interpretation in this setting are lacking. METHODS In this p...

UNLABELLED The aim of this study was to determine the diagnostic accuracy of (18)F-FDG PET/CT bronchoscopy for the detection of regional lymph node metastases in non-small cell lung cancer (NSCLC) patients; potential differences in the maximum standardized uptake value (SUVmax), mean SUV (SUVmean), short-axis diameter, and distance to the airways when comparing true-positive (TP), false-positiv...
